Compatibility: With the devices I tested there were no problems, neither in connecting, even at the sound quality. The following devices so far I could successfully try .:
Nokia N97, HTC Hero, HTC Legend, HTC Desire HD, HTC Desire Z, iPhone 4 (S), iPhone 3G (S) Belkin USB Mini Bluetooth adapter on my PC, IBM / Lenovo Notebook T60 & T410 and MacBook Pro / Air notebook. At the rear is still a 3.5mm input for older devices without BT.
I had never been the problem, that I had to pair a device after Deactivating again by BT, as described in other reviews. The connection is simply resumed when BT is turned back on. On the contrary, I can even turn the box by clicking with the remote phone.
Optics: The device looks chic: black piano lacquer and clear lines. But of course you can also see every fingerprint on the device. ;-)
Criticism: The box must always be fueled by power cables, an integrated battery would not hurt. There would also be with battery even more potential uses for the box. Why oh just 4 points.
Conclusion: Otherwise, I am completely convinced of this Creative Product. I use it very often, especially in the bathroom, bedroom and even in the garden.
